The R&ER Preservation Society is pledged to support the Railway Company. It provides financial support, and practical help through the volunteer workforce and the running of its locomotives River Mite and Douglas Ferreira.

'Whillan Beck' is the new steam engine for the railway. She was launched on 5 May 2018. The Preservation Society ran a two-and-a-half year project to buy and refurbish a 15" gauge steam locomotive, built by Krauss in Munich in 1929 and stored in Spain since the 1930s.
